Power braces is body rigidity parts, designed to reinforce structural weak point of under floor or inside of engine room, or where usually receive strong power from suspension. To install this part, there are two ways; tightening with genuine bolt together or using hole originally holed on body. Even if the length of bolt is not enough or just is hole but no bolt on standard, install bolt is including, so you don’t have to buy extra pieces. It depend on vehicle model, but its line up is set each section as front / rear or front/centre/rear separately, Of course fitting all section will offer best effect, but if you try from one, it’s recommended to use from Front where you can feel the effect easily. At here, I show you line up for Toyota Estima ( Previa / Tarago= ACR50W), but you can see all line up of power braces at catalogue page from the link in below.
